API Improvements

    - Removed 'rlen' return parameters there not necessary for multibyte encodings
    - Two versions of recode functions: rccRecode -> rccRecode, rccSizedRecode
    - Class Types: CONST, SKIP_SAVELOAD
    - New recode functions: rccToCharset, rccFromCharset
    - More new recode functions: rccRecodeToCharset, rccRecodeFromCharset, rccRecodeCharsets
    - New function: rccGetCompiledConfiguration
    - All warnings are fixed
    - Perform "File Name" search only if there are non ISO8859-1 chars in the name.
    - Do not copy invalid characters, - skip them.
    - Fixed error in rccRecode with 'Recoding Cache' switched On.
    - Strip leading and trailing spaces in rccDB4 get/set
